摘　　要：建筑外窗是太阳辐射热进入建筑室内的主要途径,要降低夏季建筑能耗、保证室内环境舒适性,外窗遮阳技术的应用十分必要。现有建筑外窗遮阳装置根据安装位置的不同,可分为内遮阳、外遮阳和玻璃自遮阳三种;根据遮阳装置的可调节程度,可分为固定式、半固定式和可收缩式三种。该文通过调研分析发现,现有各种遮阳技术都存在一定缺陷,而理想的遮阳设施应做到遮阳比例灵活可调,遮阳与采光、通风兼顾,早晚可收起,抗风雨,无高空坠落风险,安装维护方便,费用经济可行。要满足这些要求,应从多方面入手开展深入研究,综合协调处理好建筑遮阳、采光、通风、建筑安全、建筑美学等各要素之间的关系。The external window is the dominating way for solar heat to enter building indoor space.In summer,it is a necessity to apply the external window shading technique to reduce building energy consumption and ensure indoor comfort.According to installation positions,the existing external window shading devices can be classified into three types:inner shading,external shading,and glass self-shading,and according to the adjustability,they can be sorted as:fixed shading,semi-fixed shading,and retractable shading.This paper found through research and analysis that some fatal flaws lie in existing shading techniques,and the idealized shading devices should have advantages like flexible and adjustable shading ratios;solar shading combined with natural lighting and natural ventilation,portability,fastness,no risk of high-altitude falling,easy to install and maintain,and cost-effectiveness,etc.To meet these requirements,in-depth studies should be conducted on a number of aspects,comprehensively coordinating the functional requirements of solar shading,natural lighting,natural ventilation,building safety,philosophy of architecture,and so forth.
